Description

  The present invention relates to a packaging film that covers a product pack such as fruits and vegetables or directly wraps a product.

  In retail stores such as supermarkets, products such as fruits and vegetables are placed in packs (including trays) that are open on the top side, and a packaging film is placed over the opening of the pack, or products such as Chinese cabbage are placed on the packaging film. In many cases, the product is sold in a state wrapped directly in

  As this packaging film, for example, there is one shown in Patent Document 1. The packaging film is a long film having a certain width wound around a core material in a roll shape, and an adhesive surface having a certain width toward the film length direction on the back surface of at least one end. Is formed. In the packaging operation using the packaging film, the packaging film wound up in a roll shape is unwound by a necessary length, cut and pasted on a container to be packaged. A cutting line such as a perforation can be previously attached to the packaging film for every predetermined length (see FIG. 1 of Patent Document 1, paragraphs 0006 to 0009, etc.).

JP-A-9-58743

  Since the packaging film having the configuration shown in Patent Document 1 is wound in a roll shape, the packaging film may be wound during storage, and may be difficult to work when rolled out when rolled. In addition, when the packaging film is pulled by hand (by applying tension) and cut along the cutting line, the packaging film adheres to the adhesive surface formed on itself due to a change in tension at the moment of cutting. Sometimes become useless.

  Accordingly, an object of the present invention is to easily cover or wrap a product with a packaging film having an adhesive layer formed on the back side.

  In order to solve the above-mentioned problems, the present invention has a plurality of planar films formed in a predetermined shape and provided with a pressure-sensitive adhesive layer on the back surface side, and each film has the front and back surfaces in the same direction. The film for packaging which comprises the film laminated body was comprised by laminating | stacking by the said adhesion layer and adhering to each other by the said adhesion layer.

  As described above, since a plurality of planar films are laminated to form a film laminate, the film is not rounded when the films are peeled from the film laminate one by one. For this reason, work can be performed smoothly. Moreover, since each film is formed in a predetermined shape in advance and does not need to be cut at the time of use, there is no possibility that the film becomes crumpled along with the cutting.

  In this packaging film, the film may be rectangular, and an adhesive layer may be provided on two opposite sides of the film. For example, after covering the opening after storing products such as strawberries in a rectangular parallelepiped pack whose upper surface is opened, the adhesive layer is attached to the bottom surface or two opposite sides of the pack, respectively. By fixing the film, the product stored in the pack can be reliably protected.

  Moreover, in this packaging film, the said film is rectangular shape, It can also be set as the structure by which the adhesion layer is provided in the any one side of the said film. For example, products that are often sold without being put in a pack such as Chinese cabbage are wrapped directly in a film, and the adhesive layer is attached and fixed on the film surface to secure the product. Can be protected with a film.

  In said packaging film, it can be set as the structure by which the protective member which protects the said adhesion layer provided in the said film is provided in the back surface of the film of the back surface side which comprises the said film laminated body. Thus, by providing the protective member, it is possible to prevent the adhesive layer provided on the film on the backmost side from sticking to peripheral equipment such as a work table. Moreover, since the protective member acts as a reinforcing material that reinforces the bending strength of the film laminate, it is possible to prevent the film laminate from being bent and causing damage to the film.

  In this device, since the film laminate is composed of a plurality of planar films formed in a predetermined shape and provided with an adhesive layer on the back surface side, the films are peeled from the film laminate one by one. When used, the packaging film does not curl. For this reason, the operation | work etc. which put the peeled film on a pack can be performed smoothly. Moreover, since each film is formed in a predetermined shape in advance and does not need to be cut at the time of use, there is no possibility of the film becoming crumpled along with this cutting. For this reason, it is possible to prevent the film from being wasted.

The perspective view which shows 1st embodiment of the film for packaging which concerns on this application Sectional drawing which follows the II-II line in FIG. The perspective view which shows the usage example of the film for packaging shown in FIG. The perspective view which shows 2nd embodiment of the film for packaging which concerns on this application (A), (b) is a perspective view which shows the usage example of the film for packaging shown in FIG.

  A first embodiment of a packaging film according to this device is shown in FIGS. This packaging film is used for a product M that is sold in a state where the film 1 is covered with a pack P such as a strawberry (see FIG. 3). This packaging film has a film laminate 2 formed by laminating a plurality of planar (typically about several hundred) films 1 formed in a rectangular shape. On the two opposite sides on the back side of each laminated film 1, a strip-shaped adhesive layer 3 is provided. Adhesive layer provided on the back side of the upper film 1 among the laminated films 1 by laminating the front and back surfaces of the film 1 in the same direction (the front surfaces of all the films 1 face up and the back faces face down) 3 sticks to the surface side of the film 1 below the film 1. Thereby, all the laminated | stacked films 1 will be in the state bonded together sequentially via the adhesion layer 3, and the several film 1 is hold | maintained without shifting | deviating.

  A protective member 4 is provided on the back surface of the film 1 on the most back surface side constituting the film laminate 2. The protective member 4 is attached to the adhesive layer 3 provided on the back side of the film 1 on the back side, and serves to protect the adhesive layer 3. Thus, by providing the protective member 4, the adhesive layer 3 on the backmost surface is inadvertently attached to a surrounding article such as a workbench, and the adhesive force of the adhesive layer 3 decreases or the workability decreases. Can be prevented.

  As the material of the film 1, for example, it is preferable to employ stretched polypropylene (hereinafter referred to as “OPP”) in which a surface (in this embodiment, the back surface) that is on the product side during use is subjected to an antifogging treatment. The OPP film subjected to the anti-fogging treatment has high transparency and does not cause fogging on the inner surface of the film 1 due to moisture of the product, so that high visibility of the product M (see FIG. 3) can be ensured. Moreover, since it is excellent in printability, a brand name, a picture, etc. can be printed neatly on the surface of the film 1, and a high sales promotion effect can be exhibited. In addition, since it does not generate toxic gas during incineration, it is also environmentally friendly. The material of the film 1 is not limited to the above, and other materials such as general-purpose resins such as polyethylene terephthalate and polyvinyl chloride, and biodegradable plastics with a smaller environmental load can be appropriately employed.

  Although it does not specifically limit about the adhesive used for the adhesion layer 3, As long as the safety | security of the accommodated goods M can be ensured, it can select suitably.

  The protective member 4 is preferably the same shape as the film 1. Thus, by making it the same shape, the said protective member 4 protrudes from the edge part of the film laminated body 2, and while preventing it at the time of storage, the film laminated body 2 is reinforced. Further, when the film laminate 2 is held by hand, it is possible to prevent the film 1 from being bent and forcibly stretched and deformed. As this protective member 4, cardboard is used in this embodiment, but other members such as a resin plate can also be used.

  When using the packaging film according to the first embodiment, the packaging film is placed on a work table or the like so that the back side of the film 1 faces downward. And the film 1 of the outermost surface side of the film laminated body 2 is turned up one by one by hand, and is peeled off. As shown in FIG. 3, the peeled film 1 is placed on a pack P on which products M such as fruits and vegetables are stacked. And the adhesion layer 3 provided in the two opposite sides of the back surface of the film 1 is affixed on the side surface which the pack P opposes. Thus, the product M can be protected by covering the product 1 with the film 1.

  Since the said film 1 is laminated | stacked with the flat form, it does not stick around during the storage like a roll-shaped film. For this reason, when peeling, the film 1 is not rounded and the film 1 can be smoothly covered on the pack P. Moreover, since each film 1 is formed in a predetermined shape in advance and does not need to be cut at the time of use, there is no possibility that the film 1 becomes crumpled along with this cutting. For this reason, it is possible to prevent the film 1 from being wasted.

  A second embodiment of the packaging film according to this device is shown in FIGS. 4 and 5 (a) and 5 (b). This packaging film is used for products sold in the state of being directly wrapped in the film 1 without being put in a pack such as Chinese cabbage (see FIG. 5B). This packaging film is common to the packaging film according to the first embodiment in that it is a film laminate 2 formed by laminating a plurality of planar films 1 formed in a rectangular shape. On the other hand, it differs from the packaging film according to the first embodiment in that the band-like adhesive layer 3 is provided only on one side of the back side of each laminated film 1.

  By laminating the front and back surfaces of the film 1, the adhesive layer 3 provided on the back surface side of the upper film 1 in the laminated film 1 is attached to the surface side of the lower film 1 of the film 1, and the film The laminate 2 is configured. This film laminate 2 is different from the film laminate 2 according to the first embodiment, because the adhesive layer 3 is not provided on the side opposite to the one side on which the adhesive layer 3 is provided. The film 1 can be turned freely from the side where it is not provided.

  As a raw material of the film 1, it is preferable to use OPP which has been subjected to anti-fogging treatment on the surface on the product M (see FIG. 5A) side when used, as in the first embodiment.

  When using the packaging film according to the second embodiment, the packaging film is placed on a work table or the like so that the back surface side faces upward. After this placement, the protective member 4 provided on the back side is peeled off to expose the adhesive layer 3. And as shown to Fig.5 (a), the products M, such as a Chinese cabbage, are put on the film laminated body 2 (the back side of the film laminated body 2 (film 1)), and the adhesion layer 3 of the film 1 forms. The product M is rolled from the side that is not, and the film 1 on the back side is wound around the product M. When the film 1 is wound to the end, the adhesive layer 3 provided on the back surface side of the film 1 is attached to the front surface side of the film 1, and the film 1 is applied to the product M as shown in FIG. It is fixed in the wound state.

  In the above procedure of use, the protective member 4 is peeled off before the film 1 is wound around the product M. However, as described above, the product M is placed with the product M placed on the back side of the film laminate 2. Instead of winding the film 1 around the film 1, the film 1 on the outermost surface side of the film laminate 2 may be peeled by hand by hand, and then the peeled film 1 may be wound around the product M. In this case, it is preferable to leave the protective member 4 on the back side of the film laminate 2.

  The above embodiment is merely an example, and as long as the problem of this invention of easily covering or wrapping the product M with the packaging film having the adhesive layer 3 formed on the back side can be solved, the film 1 The configuration, such as the shape, the material thereof, and the position of the adhesive layer 3, can be changed as appropriate.
